(SP3T) Single Pole Three Throw Pin Diode Switches
SP3T Single Pole Three Throw Pin Diode Switches
High Speed RF and Microwave Switching
SB3 SMA Series
Taylor Microwave SP3T Pin Diode Switches provide reliable RF switching between three output ports with low insertion loss and high isolation.
The SB3 Series is available in several frequency ranges and can be customized for specific RF power handling isolation switching speed and mechanical requirements.
Key Features
10 MHz to 32 GHz
Broad frequency coverage for RF and microwave applications.
Low Insertion Loss
Designed for efficient RF signal routing with low signal loss.
High Isolation
Isolation up to 60 dB is available on standard models.
Fast Switching
Switching speeds down to 10 ns are available.
Description
The SB3 Series SP3T Pin Diode Switches are designed to route an RF signal from one common input to one of three output ports.
The switches cover multiple frequency bands and use stripline or microstrip construction selected according to power handling isolation frequency range and custom integrated assembly requirements.
Standard units use a nominal 50 Ohm impedance and are available with integral TTL or CMOS drivers and either single or dual operating supplies.
